This invention relates to a combined water motor and pump.

A primary object of the invention is to provide an apparatus formounting in a stream having a comparatively swift current, whichapparatus includes a double acting force pump driven by the motor fordelivering water from the stream to any desired point.

Another objectis to so construct such a pump that a maximum quantity ofwater may be pumped with a minimum expenditure of power,andwhich afterthe initial cost of installing is paid, operates without any expensewhatever, for an indefinite period, and then only slight repairsincident to wear become necessary. n

In carrying out these objects, the invention is susceptible of a widerange of modification without departing from the spirit or sacrificingany of the advantages of the claimed invention, there being shown in thedrawings for illustrative purposes a preferred and practical form, inwhich,

Figure l represents a diagrammatic perspective view showing thisimproved apparatus mounted in a stream ready for use,

Fig. 7 is a transverse section taken on the line 7 7 of Fig. 5, and

Fig. 8 is a similar view taken on the line 8 8 of Fig. 5.

In the embodiment illustrated, a floating dam l is shown which isdesigned to be mounted in a stream and anchored to the banks thereof,cables 2 being here shown for this purpose, secured to the front cornersof the float and to pulleys 2EL which travel on a cable 2b attached tosuitable anchors 3 on the banks of the stream. An endless cable 2G isfastened to the pulleys 2a and is trained around a pulley 2d on the post3 and conthe rise and fall of the water and yet prevents it from beingswept downstream when the current is swift. By using a windlass 70 inconnection with the cable 2C the dam may be moved toward or away fromthe banks of the stream.

This improved floating dam l comprises a central longitudinal extendingchannel chamber 5 with upstanding longitudinally extending pontoons orair chambers 6 and 7 de# signed to render the apparatus buoyant, andwhich may be of any desired height and length, according to the size ofthe stream in which the apparatus is to be located. The front ends ofthese air chambers 6 and 7 are inclined inwardly, as shown at S andoperate to direct the water passing downstream into the channel 5 sothat it passes through said channel with considerable force and operatesa waterwheel l0 revolubly mounted in the channel at its rear end, as isshown clearly in Figs. 1 and 2. rThe bottom of the channel 5 extendsforwardly in advance of the inclined ends of the air chambers and formsa platform 9 as is shown clearly in Fig. 2. This platform `9 ispreferably tapered to a point at the front end thereof, asv shown at 9FLand operates to facilitate the ent-rance of the water to the channel 5.

The waterwheel 10 is carried by a shaft 1l which extends transverselyacross the channel 5 above the topsof the chambers 6 and 7 and isjournaled in suitable bearings mounted on said tops. This shaft 1l alsoextends at one end beyond one side of the float, as is shown clearly inFig. 2 and has connected A withl its projecting end a crank arm 12 whichwhen the shaft is rotated by the turning of the wheel l0 under theinfluence of the swift current passing through the channel 5, operatesto drive the plunger of a pump 2() which is here shown mounted on thefloat at one side thereof. To provide for the mounting of this pump 2Osuitable transverse bars or beams 13 are secured to the bottom of thefloat and project at one end beyond one sideV thereof and have mountedthereon the pump 20 which is secured to said beams by U-bolts or hangers14.

The pump 20 comprises a barrel 21 of any desired size and lengthaccording to the quantity of water to be pumped thereby, and on the endsof this barrel 21 are mounted shaped chambers 22 and 32. @ne end of eachof these chambers 22 and 32 is secured to the ends of the barrel 21 andthe shank portions 23 and 33 thereof have discharge pipes mountedthereon and numbered 40 and 50. These pipes 40 and 50 are detachably connected with the shanks of the Eshaped chambers by suitable couplings 41and 51 and Within said couplings are providedi check valves 42 and 52which are designed to open to let the water out and to close when thewater is being@ drawn in to the chamber through the inlets 25 and 35which are located in the ends of the heads opposite to those connectedwith the pump barrel. These inlet ends are equipped with inwardlyopening inlet valves 24 and 34.

A double acting pump plunger 3S is mounted in the barrel 21 and as showncomprises a cylindrical member 37 provided at its opposite ends withpistons 3S and 39 and through which extends a rod which strengthens theplunger and holds the piston 10 in place. Mounted in the cylinder 3Tmidway the length thereof is a head 44 which has arms 45 and 46projecting laterally therefrom and which extend through slots 21a in thepump barrel. A rod 47 extends transversely through the head 44 and thearms 45 and 46 thereof and strengthens said head, said rod alsoextending through an ey-e formed in the rod 43. This rod 47 projectsbeyond opposite ends of the arms 45 and 46 and has connected therewiththe free ends of a yoke shaped pitman 43, this pitman 48 having its freeends inclined downwardly and inwardly toward the pump barrel and saidends straddle the barrel is shown clearly in Fig. 2. This yoke alsostraddles the delivery pipe 50 and is connected at its rear end with thecrank arm 12 by means of a connecting link 49 fixed to the yoke andpivotally connected with a stud 12a projecting laterally from the freeend of the arm 12. It is thus seen that when the shaft 11 is rotated,that the pump plunger 36 will be reciprocated and draw water first intoone chamber and then in the other alternately expelling the water fromthese chambers through the discharge pipes 40 and 50. A horizontallydisposed pipe connects the pipe 50 with the pipe 40 and merges into asingle pipe 61 through which the water is conducted to any desired placeof deposit.

From the above description it will be ob- Vious that this combined pumpand water motor, when once installed in a stream, as shown in Fig. 1,will operate indefinitely without any expense or attention.

mames It will also be obvious that the pump 20 may be detached from thecrank arm 12 of the water motor and connected with any other suitabledriving power.

Without further description it is thought that the features andadvantages of the in vention will be readily apparent to those skilledin the art, and it will of course be understood that changes in theform, proportion and minor details of construction may be resorted to,without departing from the spirit of the invention or its scope asclaimed.

I claim i In a pump, a cylinder having a detachable inlet and outlet ateach end and further provided with a pair of longitudinally entendingslots at diametrically opposite points, a double acting piston slidablymounted in the cylinder, laterally extending lugs projecting therefromat diametrically opposite pointsI and extending through the slots, arectilinear cross head mounted in said piston, projecting through saidpiston and providing an aperture, a rod extending transversely throughthe piston and the aperture of said block and passing through the lugswith the ends thereof extending beyond the lugs, a longitudinallyextending rod secured at the ends of said piston, extending through theaperture in said block and having an eye ceiving said transverse rod anda forked lever secured on the ends of the transverse rod against theends of the lug.
